Trusted Puzzle Solvers without Clock Support against Spam and Denial-of-Service Attacks
- Jiangnan Institute of Computing Technology, Wuxi, China
Abstract
Spam and Denial-of-Service (DoS) attacks aregrowing threats on the Internet. Cryptographic puzzles canbe used to address the problem effectively. Additionally, theTrusted Puzzle Solver (TPS), which is similar to the TrustedPlatform Module (TPM), is also proposed to helpconstructing crypto puzzles that may have some outstandingspecialties in security and efficiency. Based on the analysisand discussion of two existing crypto puzzles relying on theTPS with a trusted clock, two new improved crypto puzzlesare presented, and all the drawbacks found in the old onesare eliminated. The TPS in the new crypto puzzles doesn’thave to be equipped with a clock thus can be realized by theTPM without modification. Also, prototype experimentsshow that the new crypto puzzles can do better in mitigatingDoS attacks.
